This study examines SO-spindle coupling in trauma-exposed individuals and finds it predicts fear extinction retention, with PTSD showing altered coupling dynamics.

The paper identifies theta oscillations as a mechanism for tagging memories during learning, which predicts sleep-dependent consolidation through coupling with slow oscillations and sleep spindles.

The paper examines sleep spindle activity and memory consolidation in early psychosis patients and their relatives, finding spindle deficits and memory issues in patients but not relatives.

This study shows that targeted memory reactivation during NREM sleep improves neutral memory but not negative memory, with sleep spindles mediating the effect for neutral items.

This study investigates how verbal and non-verbal retrieval cues affect memory reactivation in sleep, finding verbal cues elicit stronger spindle activity than non-verbal cues.

This study links increased beta band spectral power during sleep to impaired recall of extinguished fear in both healthy individuals and PTSD patients.

The paper investigates how emotional memory consolidation during sleep stages affects memory retention, finding that reactivating memories during slow wave sleep enhances them, while reactivation during REM impairs them.

The paper examines EEG microstate dynamics during post-encoding rest and finds increased microstate D and decreased microstate C, associated with memory consolidation and encoding strength.

The paper shows sleep spindles help consolidate weakly encoded memories, reducing forgetting rates compared to staying awake.

The paper examines how stress affects the relationship between slow wave sleep and emotional memory, finding that slow oscillation-spindle coupling negatively correlates with memory in stressed individuals.

The paper investigates how stress and sleep affect memory of a social stressor environment, finding that NREM sleep physiology, not stress reactivity, is linked to memory retention in non-stressed individuals.
